188 ASPECTS OF BIOCHEMICAL EFFECTS 



the radical may be able to break certain \dtal linkages in some compounds, 

 whereas in other compounds no vital linkage is affected. 



Failla: 



T, C. Evans, about 10 years ago, demonstrated dilution and protection effects 

 with Arbacia sperm, which is a very different thing from the molecules of the 

 chemists and biochemists. It is interesting that the effects discussed by Dale 

 can also be detected with a living system. 



Dale: 



Evans' work is most interesting. I have discussed the matter with him here, 

 and we feel that the results indicate a surface effect on the organism. Evans' 

 work clearly points to further research in this field.
